TEMPORARY HEATING OR COOLING
If the unit is to be used for temporary heating or cooling, a
“Startup, Adjustments, and Checks” must first be performed
in accordance with this manual. Failure to comply with this
requirement will void the warranty. After the machines are
used for temporary heating or cooling, inspect the coils, fans,
and motors for unacceptable levels of construction dust and
dirt and install new filters.
CONTRACTOR RESPONSIBILITY
The installing contractor must be certain that:
• All supply and return air ductwork is in place and
corresponds with installation instructions.
• All thermostats are mounted and wired in accordance
with installation instructions.
• All electric power, all gas, hot water or steam line
connections, and the condensate drain installation
have been made to each unit on the job. These main
supply lines must be functional and capable of
operating all units simultaneously.
ROOF CURB INSTALLATION CHECK
Inspect the roof curb for correct installation. The unit and curb
assembly should be level. Inspect the flashing of the roof
mounting curb to the roof, especially at the corners, for good
workmanship. Also check for leaks around gaskets. Note any
deficiencies in a separate report and forward to the contractor.
OBSTRUCTIONS, FAN CLEARANCE AND WIRING
Remove any extraneous construction and shipping materials that may be found during this procedure. Rotate all fans
manually to check for proper clearances and that they rotate
freely. Check for bolts and screws that may have jarred loose
during shipment to the jobsite. Retighten if necessary. Retighten all electrical connections.
PRE-STARTUP PRECAUTIONS
It is important to your safety that the unit has been properly
grounded during installation. Check ground lug connection
in main control box for tightness prior to closing circuit breaker
or disconnect switch. Verify that supply voltage on line side
of disconnect agrees with voltage on unit identification plate
and is within the utilization voltage range as indicated in Appendix C Electrical Data.
System Voltage - That nominal voltage value assigned to a
circuit or system for the purpose of designating its voltage
class.
Nameplate Voltage - That voltage assigned to a piece of
equipment for the purpose of designating its voltage class
and for the purpose of defining the minimum and maximum
voltage at which the equipment will operate.
Utilization Voltage - The voltage of the line terminals of the
equipment at which the equipment must give fully satisfactory performance. Once it is established that supply voltage
will be maintained within the utilization range under all system conditions, check and calculate if an unbalanced condition exists between phases. Calculate percent voltage unbalance as follows:

HOW TO USE THE FORMULA:
EXAMPLE: With voltage of 220, 216, and 213
1) Average Voltage = 220+216+213=649 / 3 = 216
2) Maximum Voltage Deviations from Average Voltage = 220 - 216 = 4
3) Percent Voltage Unbalance = 100 x = = 1.8%

FIELD DUCT CONNECTIONS
Verify that all duct connections are tight and that there is no
air bypass between supply and return.
FILTER SECTION CHECK
Remove filter section access panels and check that filters
are properly installed. Note airflow arrows on filter frames.
BELT DRIVE MODELS ONLY
BEARING CHECK
Prior to energizing any fans, check and make sure that all
setscrews are tight so that bearings are properly secured to
shafts.
For heat pump units, the airflow must be adjusted so that the
air temperature rise falls within the ranges given stated on
Data Plate (see Appendix A - Blower Performance).
TENSION AND ALIGNMENT ADJUSTMENT
Correct belt tension is very important to the life of your belt.
Too loose a belt will shorten its life; too tight, premature motor and bearing failure will occur. Check you belt drive for
adequate “run-in” belt tension by measuring the force required
to deflect the belt at the midpoint of the span length. Belt
tension force can be measured using a belt tension gauge,
available through most belt drive manufacturers.

ing and clamps. The entire refrigeration system has been
factory charged and tested, making it unnecessary to field
charge. Factory charges are shown on the unit nameplate.
Install service manifold hoses. Gauges should read saturation pressure corresponding to ambient temperature. Charge
should be checked to obtain 12° to 15° of sub-cooling per
system (i.e. compressor circuits).

position, measure the distance from sheave to sheave using
a straightedge or a cord. This is your reference line. On multiple belt drives, an adjacent undeflected belt can be used as
a reference.
1. Turn thermostat system switch to “Cool,” and fan
switch to “Auto” and turn temperature setting as high
as it will go.
2. Inspect all registers and set them to the normal open
position.
3. Turn on the electrical supply at the disconnect.
4. Turn the fan switch to the “ON” position. The blower
should operate after a 7 second delay.
5. Turn the fan switch to “Auto” position. The blower
should stop after a 65 second delay.
6. Slowly lower the cooling temperature until the unit
starts. The compressor, blower and fan should now
be operating. Allow the unit to run 10 minutes, make
sure cool air is being supplied by the unit.
7. Turn the temperature setting to the highest position,
stopping the unit. The indoor blower will continue to
run for 65 seconds.
8. Turn the thermostat system switch to “OFF” and
disconnect all power when servicing the unit.
WARNING
EVAPORATOR FAN ROTATION CHECK (THREE PHASE MODELS
ONLY)
Check that fan rotates counter-clockwise when viewed from
the drive side of unit and in accordance with rotation arrow
shown on blower housing. If it does not, reverse the two incoming power cables. In this case, repeat bearing check.
Do not attempt to change load side wiring. Internal wiring
assures all motors and compressors will rotate in correct direction once evaporator fan motor rotation check has been
made.
ELECTRICAL INPUT CHECK
Make preliminary check of evaporator fan ampere draw and
verify that motor nameplate amps are not exceeded. A final
check of amp draw should be made upon completion of air
balancing of the duct system (see Appendix B).
REFRIGERATION SYSTEM CHECKS
Ensure the hold-down bolts on the compressor are secure
and have not vibrated loose during shipment. Check that vibration grommets have been installed. Visually check all pip-

HEAT PUMP START-UP PROCEDURE
9. Check the cooling mode for the heat pump in the same
manner as above. The reversing valve is energized
when the thermostat is placed in the cooling position.
A clicking sound should be noticeable from the
reversing valve. By lowering the temperature setting
to call for cooling, the contractor is energized. The
compressor, blower and fan should then be running.
After the cooling mode is checked out, turn the
thermostat system switch to “OFF”.
10. Turn the thermostat system switch to “HEAT” and fan
switch to “AUTO”.
12
11. Slowly raise the heating temperature setting. When
the heating first stage makes contact, stop raising the
temperature setting.. The compressor, blower and fan
should now be running with the reversing valve in the
de-energized (heating) position. After giving the unit
time to settle out, make sure the unit is supplying
heated air.
12. If the outdoor ambient is above 80°F, the unit may trip
on its high pressure cut out when on heating. The
compressor should stop. The heating cycle must be
thoroughly checked, so postpone the test to another
day when conditions are more suitable but-DO NOT
FAIL TO TEST.
If the outdoor ambient is low and the unit operates
properly on the heating cycle, you may check the
pressure cutout operation by blocking off the indoor
return air until the unit trips.
13. If unit operates properly in the heating cycle, raise
the temperature setting until the heating second stage
makes contact. Supplemental resistance heat, if
installed should now come on. Make sure it operates
properly.
NOTE: If outdoor thermostats are installed the
outdoor ambient must be below the set point of these
thermostats for the heaters to operate. It may be
necessary to jumper these thermostats to check
heater operation if outdoor ambient is mild.
14. For thermostats with emergency heat switch, return
to step 11. The emergency heat switch is located at
the bottom of the thermostat. Move the switch to
emergency heat. The heat pump will stop, the blower
will continue to run, all heaters will come on and the
thermostat emergency heat light will come on.
15. If checking the unit in the wintertime, when the outdoor
coil is cold enough to actuate the defrost control,
observe at least one defrost cycle to make sure the
unit defrosts completely.
FINAL SYSTEM CHECKS
16. Check to see if all supply and return air grilles are
adjusted and the air distribution system is balanced
for the best compromise between heating and cooling.
17. Check for air leaks in the ductwork. See Sections on
Air Flow Adjustments.
18. Make sure the unit is free of “rattles”, and the tubing
in the unit is free from excessive vibration. Also make
sure tubes or lines are not rubbing against each other
or sheet metal surfaces or edges. If so, correct the
trouble.
19.Set the thermostat at the appropriate setting for
cooling and heating or automatic changeover for
normal use.
20. Be sure the Owner is instructed on the unit operation,
filter, servicing, correct thermostat operation, etc.
REFRIGERATION PERFORMANCE CHECK
Under normal summertime (full load) operating conditions,
superheat should be between 8°F and 12°F and sub-cooling
measured at the condenser outlet should be 15°F (nominal).
A 25°F to 35°F temperature difference should exist between
the entering condenser air and the temperature corresponding to the compressor saturated discharge pressure. Check
that compressor RLA corresponds to values shown in Appendix C. RLA draw can be much lower than values listed at
low load conditions and low ambient condensing temperatures. Values in Appendix C can slightly exceed at high load
conditions and high ambient condensing temperatures.
HEAT PUMP OPERATION
COOLING CYCLE
When the heat pump is in the cooling cycle, it operates exactly as a Summer Air Conditioner unit. In this mode, all the
charts and data for service that apply to summer air conditioning apply to the heat pump. Most apply on the heating
cycle except that “condenser” becomes “evaporator”, “evaporator” becomes “condenser”, “cooling” becomes “heating”.
HEATING CYCLE
The heat pump operates in the heating cycle by redirecting
refrigerant flow through the refrigerant circuit external to the
compressor. This is accomplished with through the reversing
valve. Hot discharge vapor from the compressor is directed
to the indoor coil (evaporator on the cooling cycle) where the
heat is removed, and the vapor condenses to liquid. It then
goes through the expansion device to the outdoor coil (condenser on the cooling cycle) where the liquid is evaporated,
and the vapor goes to the compressor.
When the solenoid valve coil is operated either from heating
to cooling or vice versa, the piston in the reversing valve to
the low pressure (high pressure) reverse positions in the reversing valve.
The following figures show a schematic of a heat pump on
the cooling cycle and the heating cycle. In addition to a reversing valve, a heat pump is equipped with an expansion
device and check valve for the indoor coil, and similar equipment for the outdoor coil. It is also provided with a defrost
control system.
The expansion devices are flowrator distributors and perform
the same function on the heating cycle as on the cooling cycle.
The flowrator distributors also act as check valves to allow
for the reverse of refrigerant flow.

to 30, 60 and 90 respectively. Accumulation of time for the
timing period selected starts when the sensor closes (approximately 31° F), and when the wall thermostat calls for

will be initiated provided the sensor remains closed. When
the sensor opens (approximately 75° F), the defrost cycle is
terminated and the timing period is reset. If the defrost cycle
is not terminated due to the sensor temperature, a twelve
minute override interrupts the unit’s defrost period.

OUTDOOR
COIL
When the heat pump is on the heating cycle, the outdoor coil
is functioning as an evaporator. The temperature of the refrigerant in the outdoor coil must be below the temperature of
the outdoor air in order to extract heat from the air. Thus, the
greater the difference in the outdoor temperature and the
outdoor coil temperature, the greater the heating capacity of
the heat pump. This phenomenon is a characteristic of a
heat pump. It is a good practice to provide supplementary
heat for all heat pump installations in areas where the temperature drops below 45° F. It is also a good practice to
provide sufficient supplementary heat to handle the entire
heating requirement should there be a component failure of
the heat pump, such as a compressor, or refrigerant leak,
etc.
Since the temperature of the refrigerant in the outdoor coil on
the heating cycle is generally below freezing point, frost forms
on the surfaces of the outdoor coil under certain weather conditions of temperature and relative humidity. Therefore, it is
necessary to reverse the flow of the refrigerant to provide hot
gas in the outdoor coil to melt the frost accumulation. This is
accomplished by reversing the heat pump to the cooling cycle.
At the same time, the outdoor fan stops to hasten the temperature rise of the outdoor coil and lessen the time required
for defrosting. The indoor blower continues to run and the
supplementary heaters are energized.
AIR FLOW ADJUSTMENTS
The drive on the supply fan is typically set in the middle of the
RPM range. The drive motor sheave pitch diameter is field
adjustable for the required airflow. Refer to “Drive
Adjustments” section below.
When the final adjustments are complete, the current draw
of the motor should be checked and compared to the full
load current rating of the motor. The amperage must not exceed the service factor stamped on the motor nameplate.
The total airflow must not be less than that required for operation of the electric heaters or the furnace.
If an economizer is installed, check the unit operating balance with the economizer at full outside air and at minimum
outside air. Upon completion of the air flow balancing, we
recommend replacing the variable pitched motor sheave with
a properly-sized fixed sheave. A matching fixed sheave will
provide longer belt and bearing life and vibration free operation. Initially, it is best to have a variable pitched motor sheave
for the purpose of airflow balancing, but once the balance
has been achieved, fixed sheaves maintain alignment and
minimize vibration more effectively. For direct drive units, move
green wire for fan.
NOTE: Never run CFM below 350 CFM per ton, evaporator
freezing or poor unit performance is possible.
PSC MOTOR
Adjust the CFM for the unit by changing the speed tap of the
indoor blower motor at the EBTDR “com” connection with the
one of the speed taps on “M1” or “M2” (Black-High Speed,
Blue-Medium Speed, Red-Low Speed).
X-13 MOTOR
Adjust the CFM for the unit by changing the position of the
low voltage leads on the motor terminal block. Green is for
Fan Only. Yellow is for Cooling and Heat Pump Heating. Refer to Appendix A for blower performance at each speed tap.
NOTE: If more than one lead is energized simultaneously,
the motor will run at the higher speed.

DRIVE ADJUSTMENTS
MOTOR SHEAVE ADJUSTMENTS
VL, VM, & 2VP VARIABLE PITCH KEY TYPE MOTOR SHEAVES
The driving and driven motor sheaves should be in alignment with each other and the shafts parallel.
VL & VM SHEAVES ADJUSTMENT
1. Loosen set screw “B” using a 5/32" Allen key.
2. Making half or full turns from closed position, adjust
sheave pitch diameter for desired speed. DO NOT
OPEN MORE THAN FIVE FULL TURNS.
3. Tighten set screw “B” securely over flat.
4. Carefully put on belts and adjust belt tension. DO NOT
FORCE BELTS OVER GROOVES.
5. Ensure all keys are in place and the set screws tight
before starting drive. Recheck set screws and belt
tension after 24 hours service.

.
The Self Contained Packaged Air Conditioner and Heat Pump
should operate for many years without excessive service calls
if the unit is installed properly. However it is recommended
that the homeowner inspect the unit before a seasonal start
up. The coils should be free of debris so adequate airflow is
achieved. The return and supply registers should be free of
any obstructions. The filters should be cleaned or replaced.
These few steps will help to keep the product up time to a
maximum. The Service section that follows should help in
identifying problems if the unit does not operate properly.

SERVICE
THE FOLLOWING INFORMATION IS FOR USE BY QUALIFIED SERVICE AGENCY ONLY: OTHERS SHOULD NOT

Common Causes of Unsatisfactory Operation of Heat Pump
on the Heating Cycle.
INADEQUATE AIR VOLUME THROUGH INDOOR COIL
When a heat pump is in the heating cycle, the indoor coil is
functioning as a condenser. The return air filter must always
be clean, and sufficient air volume must pass through the
indoor coil to prevent excessive discharge pressure, and high
pressure cut out.
OUTSIDE AIR INTO RETURN DUCT
Do not introduce cold outside air into the return duct of a heat
pump installation. Do not allow air entering the indoor coil to
drop below 65° F. Air below this temperature will cause low
discharge pressure, thus low suction pressure, and excessive defrost cycling resulting in low heating output. It may
also cause false defrosting.
POOR “TERMINATING” SENSOR CONTACT
The unit’s defrost terminating sensor must make good thermal contact with the outdoor coil tubing. Poor contact may
not terminate the unit’s defrost cycle quickly enough to prevent the unit from cutting out on high discharge pressure.
MALFUNCTIONING REVERSING VALVE - THIS MAY BE DUE TO:
1. Solenoid not energized - In order to determine if the
solenoid is energized, touch the nut that holds the
solenoid cover in place with a screwdriver. If the nut
magnetically holds the screwdriver, the solenoid is
energized and the unit is in the cooling cycle.
2. No voltage at unit’s solenoid - Check unit voltage.
If no voltage, check wiring circuit.
3. Valve will not shift:
a. Undercharged - check for leaks;
b. Valve Body Damaged - Replace valve;
c. Unit Properly Charged - If it is on the heating cycle,
raise the discharge pressure by restricting airflow
through the indoor coil. If the valve does not shift,
tap it lightly on both ends with a screwdriver handle.
DO NOT TAP THE VALVE BODY. If the unit is on
the cooling cycle, raise the discharge pressure by
restricting airflow through the outdoor coil. If the valve
does not shift after the above attempts, cut the unit
off and wait until the discharge and suction pressure
equalize, and repeat above steps. If the valve does
not shift, replace it.
